[PMID: 36484492 DOI: 10.1080/1120009x.2022.2153317] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 11/06/2022] [Accepted: 11/24/2022] [Indexed: 12/13/2022]
Abstract
Bacillus cereus is a spore-forming, gram-positive bacterium that is ubiquitous in the environment. Central nervous system involvement with B. cereus is rare. Despite aggressive treatment with broad-spectrum antibiotics and using them appropriately, the mortality is high. A 72-year-old patient suffered a central nervous system infection associated with postsurgical meningitis and was successfully treated with a novel antibiotic therapy. This study includes the first case report of postsurgical B. cereus meningitis in the last ten years. It provides a different line of treatment to the previous ones.

Abstract
Observation following gross-total resection (GTR) for non-anaplastic supratentorial ependymomas is often advocated based on small, retrospective series. The purpose of this study is to perform a population-based analysis to examine outcomes for this rare cohort of low-risk patients. A retrospective analysis was conducted utilizing the Surveillance, Epidemiology and End Results Program of the United States National Cancer Institute. We identified patients with supratentorial non-anaplastic ependymoma who underwent GTR alone or GTR followed by radiation. We identified 92 patients who met these criteria. The median age was 17.5 years (range 1-83) with the majority female (58 %) and white (75 %). Radiotherapy (RT) was delivered in half of patients. The 5-/10-year Kaplan-Meier estimated overall survival (OS) and cause-specific survival (CSS) for the overall cohort was 83.2/71.4 and 84.1/78.0 %, respectively. There was no evidence of decreased CSS (HR 0.52 [0.18-1.51]; p = 0.23) or OS (HR 0.63 [0.25-1.59]; p = 0.33) with the omission of RT on univariate analysis. Age ≥18 years correlated with worse OS (HR 4.01 [1.45-11.11]; p = 0.008) and CSS (HR 2.86 [0.99-8.31]; p = 0.05). RT did not impact outcome for this low-risk cohort of patients. Older age correlates with poor prognosis.

Abstract
Species of the genus Bacillus are a common laboratory contaminant, therefore, isolation of these organisms from blood cultures does not always indicate infection. In fact, except for Bacillus anthracis and Bacillus cereus, most species of the genus Bacillus are not considered human pathogens, especially in immunocompetent individuals. Here, we report an unusual presentation of bacteraemia and mediastinitis due to co-infection with Bacillus subtilis and Bacillus licheniformis, which were identified by 16S RNA gene sequencing, in a patient with an oesophageal perforation.

Abstract
Many Gram-positive spore-forming bacteria in the Firmicute phylum are important members of the human commensal microbiota, which, in rare cases, cause opportunistic infections. Other spore-formers, however, have evolved to become dedicated pathogens that can cause a striking variety of diseases. Despite variations in disease presentation, the etiologic agent is often the spore, with bacterially produced toxins playing a central role in the pathophysiology of infection. This review will focus on the specific diseases caused by spores of the Clostridia and Bacilli.

Abstract
Nosocomial infections in neonatal intensive care units are a preoccupying issue. Bacillus sp. can be pathogenic in immuno-compromised hosts, including premature infants. Central catheters and mechanical ventilation are potential sources of infection. We report for the first time a case of Bacillus licheniformis bacteremia in a premature infant. Recovery necessitated treatment with vancomycin and cefotaxime in combination with removal of the central catheter.

Abstract
A small study was undertaken to examine the microbiological characteristics of spent mushroom compost (SMC), which is the major waste by-product of the mushroom industry and which is regularly disposed off by application to agricultural land. The primary aim of this study was to examine SMC for the presence of faecal bacterial pathogens, including Campylobacter spp., Salmonella spp. and Listeria monocytogenes. Secondly it was desirable to quantify bacterial and fungal populations within SMC, and also qualitatively identify the diversity of bacterial populations within SMC, through employment of rDNA PCR and direct sequencing techniques on the culturable microflora. Conventional microbiological analyses of SMC material (n=30) from six commercial operations in both Northern Ireland and the Republic of Ireland, failed to detect Salmonella spp, Listeria spp. or Campylobacter spp. in any of the SMC material examined. Total aerobic plate counts gave a mean count of log10 7.01 colony forming units (cfu) per gram SMC material (range: log10 6.53-7.52 cfu/g). Fungal counts gave a mean count of log(10) 4.57 cfu per gram SMC material (range: log10 3.93-4.98 cfu/g). From a total of greater than 50 colony picks, a total of 12 bacterial morphotypes were identified and were further examined by employment of partial 16S rRNA gene amplification and sequencing techniques, yielding several genera and species, including Bacillus licheniformis, Bacillus subtilis, Klebsiella/Enterobacter sp. Microbacterium sp. Paenibacillus lentimorbus, Pseudomonas mevalonii, Sphingobacterium multivorum and Stenotrophomonas sp. This is the first preliminary report on the microbial diversity of SMC waste and demonstrates the presence of several species that have not been previously described in SMC, in addition to two potentially novel species within the genera Microbacterium and Stenotrophomonas. It is thereby important to examine the ecological microbe-microbe and plant-microbe interactions that are occurring between the native bacterial soil flora and those added annually (theoretically estimated at approximately 10(18) cells) through the application of SMC. Such studies would be beneficial in helping to ascertain the ecological consequences involved in the disposal of SMC waste on agricultural land.

Abstract
This study was initiated because of an increase in diarrhoeal episodes in a ward caring for patients infected with the human immunodeficiency virus (HIV). An examination of hospital-prepared dietary supplements (build-up food) found Bacillus cereus to be a potential problem. Due in part to inadequate refrigeration conditions (13 +/- 4 degrees C), the microbial flora in commercially pasteurized semi-skimmed milk (PSSM) reached potentially hazardous levels (> 10(6) cfu/mL). While refrigerated PSSM did not support enterotoxin production, reconstitution of build-up powder in PSSM followed by storage in the HIV ward (4 h at 28 +/- 3 degrees C) resulted in growth of B. cereus (> 10(7) cfu/mL) and synthesis of diarrhoeal enterotoxin. While insufficient epidemiological data was available to establish conclusively a causal relationship between patients' symptoms and source, the study highlights a potential B. cereus problem with hospital-prepared dietary supplements and recommendations are proposed to prevent this re-occurrence.

Abstract
A 73-year old man developed an acute prosthetic aortic valve dehiscence for which emergent operation was undertaken. The intraoperative evidence of an aortic annular disruption and of a subannular abscess led to the hypothesis that an endocarditis process was involved. The aortic valve was replaced with a stentless porcine bioprosthesis. Cultures taken intraoperatively from the aortic area had a pure growth of aerobic, spore-forming, gram-positive bacilli identified as Bacillus licheniformis. The patient responded to specific antibiotic therapy with no relapse at a 20-month follow-up. The potentiality of B. licheniformis as a pathogen should be reconsidered.

Abstract
The genus Bacillus is a diverse group of gram-positive, spore-forming aerobic bacilli. B anthracis, the agent of anthrax, is primarily an animal pathogen but is capable of causing human infection, most commonly of the skin or lungs. B cereus, a well-recognized cause of gastroenteritis, may occasionally cause epidemics in health institutions. Both B cereus and other Bacillus species are increasingly recognized as opportunistic pathogens in the hospitalized patient. This report is intended as a comprehensive review of the bacteriology, clinical features, and therapy of Bacillus spp infections. Nosocomial epidemics and transmission will be highlighted.
